The catchment creeks can be divided onto 32 broad sub-catchments:
Toongabbie Creek sub-catchment; Darling Mills Creek sub-catchment;
and Parramatta River Floodplain sub-catchment .
The water quality in most of the creeks is very poor for human
uses, and an average quality for ecosystem health.
Pressure:
The quality of water in the creeks is caused by urban living
such as driving cars and developments. These activities produce
pollution such as nutrients, chemicals, litter and sediment
that reduce the quality of water.
Response:
Improving and maintaining a good level of water quality is
the responsibility of everyone. Governments are putting alot
of money to help improve water quality. The Trust works with
local councils and the community on many projects to improve
water quality.
